Fairfax area public safety officials have offered Halloween safety tips and other suggestions on how to enjoy the fun Sunday night:

* The City of Falls Church Sheriff's Office will hand out about 500 treat bags while on patrol between 5 p.m. and midnight Sunday. The bags contain candy, pencils, small toys and crime prevention tips. Sheriff's deputies and their families and friends assemble the bags. The program is designed to help deter unsafe behavior in residential areas. For more information, call 703-248-5111.

* The McLean-based Washington Regional Alcohol Program will offer free cab rides between 8 p.m. Saturday and 4 a.m. Sunday and between 8 p.m. Sunday and 4 a.m. Monday. The idea is to keep alcohol-impaired drivers off the road. To receive a free (up to $50 fare) cab ride home, call 800-200-8294 or press #8294 (TAXI) on an AT&T Wireless telephone. You must be 21 or older. The program covers Fairfax County and the cities of Falls Church and Fairfax. For more information, go to www.soberride.com.

* County public safety officials advise young trick-or-treaters: Go with at least one adult; drop by homes of people you know; and do not eat candy until you are home where an adult can inspect the treats to see if anything has been tampered with.

Officials also are advising parents to use makeup instead of masks for their children's costumes because masks can limit their field of vision; give their children flashlights; and stick reflective tape on outfits and shoes.

If your child does wear a mask, it should be removed so the child can look both ways before crossing the street.
